Answer:

The solution is -10

Step-by-step explanation:

We first solve for v in the equation;

5v + 9 = 4

5v = 4 - 9

5v = -5

v = -1

Finally, we substitute v = -1 in the given expression;

3v - 7

3(-1) - 7 = -10

Answer:

-10 is the answer.

Step-by-step explanation:

We have given equation:

5v +9=4​

We have to find the value of  3v-7.

To find the value of v we use the given equation.

5v +9=4​

5v = 4-9

5v = -5

v = -1

Putting v = -1 in the equation  3v-7 to get the required answer.

3v-7 = 3(-1)-7

3v-7 = -3-7

3v-7 = -10   is the solution.
